Hello,
It is best practice to use the wachdog fucntion to recover the arduino when it bolck.
today the arduino stuck when arrives to 60000 seconds of use and until go back home was no posibility to restart it.
I just inplement this code, It is OK or really has no vaule on the sketch?
#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <CayenneMQTTESP8266Shield.h>
#include “DHT.h”
#include <avr/wdt.h>
int amarillo = 0;
int blanco = 0;
// WiFi network info.
char ssid = “xequebo”;
char wifiPassword = “0”;
// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username = “80”;
char password = “0”;
char clientID = “0”;
// Set ESP8266 Serial object. In this example we use the Serial1 hardware serial which is available on boards like the Arduino Mega.
#define EspSerial Serial
#define DHTPIN 7
#define DHTTYPE DHT11
ESP8266 wifi(&EspSerial);
DHT dht(DHTPIN, DHTTYPE);
void setup()
{
wdt_disable();
pinMode(12, OUTPUT);
pinMode(13, OUTPUT);
Serial.begin(9600);
delay(10);
dht.begin();
// Set ESP8266 baud rate
EspSerial.begin(9600);
delay(10);
Cayenne.begin(username, password, clientID, wifi, ssid, wifiPassword);
wdt_enable(WDTO_8S);
}
void loop()
{
Cayenne.loop();
wdt_reset();
}
// Default function for sending sensor data at intervals to Cayenne.
// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.
CAYENNE_OUT_DEFAULT() {
float h = dht.readHumidity();
float t = dht.readTemperature();
Cayenne.luxWrite(2, analogRead(1));
Cayenne.virtualWrite(4, h, TYPE_RELATIVE_HUMIDITY, UNIT_PERCENT);
Cayenne.virtualWrite(3, t, TYPE_TEMPERATURE, UNIT_CELSIUS);
Cayenne.virtualWrite(0, millis() / 1000);
}
CAYENNE_IN(12)
{
amarillo = getValue.asInt();
CAYENNE_LOG(“Channel %d, pin %d, value %d”, 12, 12, amarillo);
digitalWrite(12, amarillo);
}
CAYENNE_IN(13)
{
blanco = getValue.asInt();
CAYENNE_LOG(“Channel %d, pin %d, value %d”, 13, 13, blanco);
digitalWrite(13, blanco);
}
